Display freezes on games, hard reset needed

[gabrielsim1993]

Hi all,

I'm having quite a headache from trying to troubleshoot this issue.

CPU: Intel i-5 3470
GPU: Asus HD 7750
Mobo: Asrock Z77 Extreme4
Display: Dell 23" 1920 x 1080 (16:9)

Whenever I play Fifa 12 or Fifa 13(newly bought and updated), the screen turns to a fixed colour (usually white or green, with stripe pattern) within 3 - 15 minutes. The computer hangs, all input devices don't seem to do anything but the audio continues and I have to hard reset it.

This problem only occurs when I use the dedicated GPU. I don't get problems by using the onboard graphics (straight to mobo) but the game is quite lag, understandably.

However, the Asus HD7750 does not give me a single problem when I play Warcraft 3, or use any other windowed programs for an extended period of time. I do not think PSU has got to do with this problem.

Directx and catalyst control, mobo bios are all up to date.

I'm suspecting it to be a software problem, probably something to do with directx but I cannot trace it down. Dxdiag shows no problem, but should I try downgrading from DX11 to DX9? Will it solve?

Are you monitoring your system temperatures (CPU and GPU primarily)? If so, how hot are these components getting under load? If you aren't monitor, get and install hwmonitor (see below) and get the info. You are describing the typical symptoms of a heat and/or power issue. Also, what make/model of power supply are you using?

HWMonitor shows my gpu temperature at around 50° C. So it shouldn't be overheating problem. As for power, I am using Cooler Master GX 500W Bronze. Is there any way to check whether my computer is receiving insufficient power?

Is 50C at idle or under load? Also, what, if anything, are you overclocking (CPU, GPU, or memory)?

50C - 55C under load. I alt tab while playing FIFA 13 to check the temperature.

I just played an hour over of Warcraft 3 and then switched over to FIFA 13 for less than 5 minutes and it has freezed my whole computer again.

CPU / Memory not overclocked. GPU is Asus HD 7750 which is factory overclocked up 20mHz.

From what I can see is the screen resolution and directx version in both games.

Warcraft 3: 1280 x 1024, DirectX 8
FIFA 13: 1920 x 1080, DirectX 9

WoW is putting a much lower load on the GPU due to the lower resolution. FIFA is making your GPU work much harder. If you ran WoW at 1920x1080, does your system hang?

I installed FurMark and ran graphics test on both the Intel 2500 graphics and Asus HD 7750.

Intel's one remained at 2fps throughout, while HD 7750 was at 9fps. However, the display freezed within 2 minutes with the Asus 7750 and display went green with stripes again. Whole computer freezed and I had to reset.

Question is:
-PSU or GPU the problem?

(PSU is Cooler Master GX 550W)

 

[COLGeek]

Do you access to another psu to swap in for testing?

 

[gabrielsim1993]

Okay i just tried it on another computer, whole system freezes again after 3 minutes of running furmark. So it should be the gpu problem?

Seems likely. Did the other computer's PSU meet the power needs of the GPU? If so, I think you have found the culprit.
